Three dimensional MREIT for breast cancer detection on open MRI scanners

Magnetic resonance electrical impedance tomography (MREIT) is a novel, noninvasive functional imaging technology that is hopeful to be applied in the diagnosis of early breast cancer. Based on the Open MRI scanners with a vertical magnetic field, the sensitivity reconstruction algorithm is developed to three dimensional space for MREIT. To cut down the computing time, the sensitivity matrix equation is solved by the Generalized Minimal Residual Krylov method for breast imaging. Simulation results with a hemisphere model show the validity and precision of the reconstruction. Phantom results based on an Open 0.36T MRI scanner show a promising application prospect for breast cancer detection by Open MREIT.
